Supporters of Mir Hossein Moussavi -- the country's top opposition candidate -- have protested daily, questioning whether the election was fair and asking for another vote. Analysts outside the country also expressed skepticism.

Ahmadinejad is a conservative who has had a rocky relationship with the West. He has earned a reputation internationally as a fundamentalist for his Holocaust denials, calls to annihilate Israel, and cat-and-mouse games with the United States and the United Nations over Iran's nuclear activities.

Moussavi, a former prime minister, is credited for successfully navigating the Iranian economy during the Iran-Iraq war, but he also is a hard-liner. He, like most Iranians in power, also does not believe in the existence of Israel.

The demonstrators in Iran say their demand is simple: Hold fresh elections. They say they are not out to challenge the Islamic regime.
